Similar experience.... I was shocked by the aggression dealt up when faced with a complaint. THe cynicism is appalling. I am not even going to bother letting the owners know. I am sure they already do. It must be the modus operandi ....from the top down... a cynical disregard for the ever patient , polite , mostly white middle class (on the night I went) customer.
Shame... the food was mostly quite nice
Overpriced and minimal selection.
My experience at cocos is: don't say anything you wouldnt say to your nana. It's a family business, a family affair.
If you went to a family dinner and complained to your sister that your steak was fatty while the rest of the family loved it, then complained that your dessert was different to everyone else's instead of thanking her for whipping up a special one, then complained when she ignores your complaining, then it's safe to say you're "that sibling" and you should dine downtown and really work on not letting such petty problems get between you and a good time.
